310 Watt LED UFO High Bay | 45000 Lumens | 5000K | 277-480V

Product Overview

This adjustable UFO high bay delivers 19,800 to 33,000 lumens through field-selectable wattage settings of 120, 160, or 200 watts. The fixture operates at 165 lumens per watt across all output levels and replaces 250 to 400 watt metal halide fixtures in industrial and commercial applications.

Color temperature is selectable between 4000K and 5000K. The fixture accepts 100-277V input at 50/60 Hz and supports 1-10V dimming. Housing is available in black or white aluminum alloy construction.

The polycarbonate lens produces a 120-degree beam angle. Rated lifespan is 134,000 hours at L70. The fixture measures 11.8 x 6.6 inches and weighs 5.1 pounds.

Where This Product Fits Best

This high bay is built for indoor industrial and commercial spaces where mounting heights and light level requirements vary across zones. The adjustable wattage allows a single fixture type to serve areas with different output needs, from aisles and workstations to open floor space.

The IP65 rating allows installation in environments with dust, debris, and occasional water spray. The IK08 impact rating provides mechanical protection against incidental contact. Operating temperature range of -22°F to 122°F supports use in cold storage vestibules, unconditioned warehouses, and high-ambient manufacturing areas.

Hook mounting suits standard pendant and chain installations on open ceilings or structural supports. The 6kV surge protection addresses electrical noise common in facilities with motors, compressors, or variable frequency drives.

Performance and Functional Considerations

Wattage selection determines lumen output: 120 watts produces 19,800 lumens, 160 watts produces 26,400 lumens, and 200 watts produces 33,000 lumens. All three settings maintain 165 lumens per watt efficiency. CRI is 80+, suitable for general industrial tasks and inventory handling.

The 4000K setting provides a neutral white appearance often used in manufacturing and assembly areas. The 5000K setting produces a cooler, daylight-type appearance common in warehouses and distribution centers. Both color temperatures are selectable on the fixture.

The 1-10V dimming input allows integration with compatible building controls or standalone dimmers. A motion sensor is available as an accessory for occupancy-based control.

Installation and Long-Term Use

The fixture installs via hook mount, compatible with chain, cable, or rigid pendant configurations. At 5.1 pounds, it handles easily during installation and does not impose significant structural load on typical mounting systems.

Wattage and color temperature selections are made at the fixture during installation or at any point afterward. No special tools or additional components are required to change settings. This allows adjustments during commissioning or if space use changes over time.

The aluminum alloy housing and IP65 seal support long service life in demanding environments. The 134,000-hour rated lifespan at L70 reduces fixture replacement frequency in hard-to-access locations.

How This Fixture Is Commonly Used

Facility operators typically set wattage based on the specific zone where each fixture is installed. Higher output settings serve open manufacturing floors or tall ceiling bays, while lower settings work for aisles, storage areas, or lower mounting heights. Adjustments are made directly on the fixture.

Color temperature is selected based on the visual character preferred for the space. Facilities that prioritize alertness and visual clarity often use 5000K. Spaces where a warmer appearance is acceptable or preferred use 4000K. Once set, the selection remains unless manually changed.

The 1-10V dimming input allows facility personnel to tie fixtures into existing dimming infrastructure or adjust output levels through compatible controls. This supports scheduled dimming, daylight response, or manual override depending on the control system in place.

Safety, Certifications, and Warranty

This fixture is ETL listed and DLC Premium qualified. The IP65 rating allows exposure to dust accumulation and direct water jets from any direction. The IK08 rating protects against moderate mechanical impact from accidental contact or falling debris.

Surge protection is rated at 6kV, addressing transient voltage events that can occur in industrial electrical environments. The operating temperature range of -22°F to 122°F defines the ambient conditions in which the fixture is rated to operate.

We provide a 5-year warranty on this fixture.
